    I'm getting quite good with all the identities and proving them, but I can't do those equations where you have to use a SACT diagram to find angles. I know it was in C2 but I never really understood it then either (only just scraped an A).

    I've looked on Examsolutions and I can't find a video that explains it. Can someone link me to a video that explains it well?

    If you look on m4ths.com you should be able to find a good video on it in one of the playlists. Alternatively you could search for it on youtube along with 'maths247' as that is the guy's channel. It'll most likely be easier to find the right video via the youtube playlist links on his site, though.
